摘要
桥梁静载试验是测量桥梁结构在试验荷载作用下的应变和挠度,它是了解桥梁结构实际工作状态的最直接有效的方法。通过对花岗岩石梁桥的石材弯曲抗拉强度、弹性模量试验方法,以及静载试验在石梁桥检测中的应用,并将实测石梁的应变和挠度与理论计算结果进行比较分析,评估石梁桥的承载能力。
The static load test of bridge is used to measure the strain and deflection of bridge structure under testing load.It is the most directive and effective method to know the actual working status of bridge structure Through the bending tensile strength and elasticity modulus test methods of stone material for granite bridge,and the application of the static load test in detection of stone beam bridge the article compares and analyzes the measured strain and deflection of stone beam with the theoretical calculation results to evaluate the bearing capacity of stone beam bridge.
